JOHN DEEBLE, OF SOUTI-IINGTON, CONNECTICUT.

NAIL-PU LLER.

SPECIFICATION forming part of Letters Patent No. 644,667, dated March 6, 1900.

Application filed November 15, 1899. serial No. 737,074. (No model.)

To all whom it may concern:

Be it known that I, JOHN DEEBLE, a citizen of the United States, residing in Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Nail-Pullers, of which the following is a specification.

My invention relates to improvements in nail-pullers; and the objects of my improvement are simplicity and economy in construction and general efficiency of the article.

In the accompanying drawings, Figure 1 is a side elevation of my nail-puller with the foot-lever in vertical and longitudinal section. Fig. 2 is an edge view of the same looking on the pivotal end of the foot-lever. Fig. 3 is a sectional plan of the same on the line :1; a: of Fig. 1.

A designates the body of the main lever, upon which an ordinary sliding hammer (not shown) maybe fitted in any ordinary manner. Extending downwardly from the said body there are two integral spring-arms t 4, that terminate in the pointed jaws 5 6, of which the jaw 5 may be of any ordinary form and to which jaw the foot-lever B is pivoted by the pin or bolt 8. The jaw 6 has on its outer edge, a short distance above its lower end, a shoulder 9, above which shoulder is an incline 10, that is eccentric to the pivotal bolt 8 of the foot-lever, as shown in Fig. 1. The foot-lever is, in the main, of an ordinary form and is bifurcated at one end, so as to receive and embrace the two jaws 5 6 between its arms, as shown. The wall at the end of the bifurcated portion of the foot-lever that faces the eccentric face or incline 10 of the jaw 6 may be made so as to substantially conform to that face when the lower edge 7 of said lever bears upon the shoulder 9, as shown in Fig. 1. The body A and spring-arms 4 t, together with the jaws 5 and 6, are of a flat plate-like form, whereby they may be cheaply constructed as one integral thing by cutting from a bar of rolled steel. They may also be cut or formed with the pointed ends of the jaws farther apart than is desired when in the position for use, so that in order to mount the foot-lever thereon in the manner shown it will be necessary to force them together a little, so that when thus mounted the footlever will hold the jaws under tension. This will cause the lower edge 7 of the foot-lever to bear with pressure against the shoulder 9 and prevent the said foot-lever from acci dentally falling down over or oif from the end of the jaw 6.

In use the jaws are placed in proper position over the head of the nail to be drawn and then driven into the wood slightly. The body A of the main lever is then forced toward the outer end of the foot-lever, which foot-lever by engaging the surface of the wood moves on its pivot against the incline 10 and forces the jaws firmly upon the nail, after which a continued movement of the body of the main lever in the same direction will draw the nail. Upon returning the lever to release it the resiliency of the arms 4. 4. spreads them apart until the edge 7 of the foot-lever is engaged with the shoulder 9, as shown.

It is. apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in working my invention as may fairly come within the spirit and scope of the same.

I am aware that a prior patent shows and describes a nail-puller having integral springjaws of a flat plate-like form and with a slotted footed lever through which the lower ends of the jaws pass, the said lever being pivoted to one of said jaws, while the wall at the end of the slot in the said lever-bears against the inclined outer edge of the opposite jaw; also, that another patent shows and describes a similar nail-puller, but with the foot-lever having in addition to the jaw-receiving slot an inclined slot on each side that is engaged by a pin or stud on one of the jaws for forcing the jaws together and for holding the footlever in position without any engagement whatever with the outer edges of the jaws. All of the above prior art is hereby disclaimed.

By my improvement a very durable and efficient implement is produced in which the wearingsurface is confined mainly to the outer edge of the jaw, while at the same time the foot-lever is held in place thereon with the jaws under tension. The implement can also be constructed at a small cost without any additional expense over the more simple form 0f implement first diselaimed and without the jaw 5 and bearing, on the incline and any frail parts that are liable to be soon i1nshoulder of the opposite-jaw, substantially as paired in use. described.

I claim as my invention- JOHN DEEBLE. 5 The combination of the arms 4, 4, and jaws Witnesses:
